Calculates the geometric mean[1] of the values in a data set.
Syntax:
GEOMEAN( list )
Returns the geometric mean of the values in the list.
list may be a range of cells, an array, or a comma-separated list of values (which may contain cell references and also ranges of cells as one or more of its elements).
All values in the list must be positive, non-zero numbers.
Formula:
GEOMEAN = ( i ∏1n xi ) 1/n
where n is the number of values and xi is the i‑th value.
Example:
GEOMEAN(A1:A15)
returns the geometric mean of the contents of cells in the range A1:A15
.
